Activation of an exact stop criterion
An exact stop criterion is activated in the part program by programming the following G-
functions:
• G601 - Exact stop fine
• G602 - Exact stop coarse
• G603 - Interpolator end
Evaluation factor for exact stop criteria
A parameter-set-related evaluation of the exact stop criteria can be specified by means of
the following axis-specific machine datum:
MD36012 $MA_STOP_LIMIT_FACTOR (exact stop coarse/fine factor and standstill)
Applications
• Adaptation of the positioning response to different mass ratios, such as after a gearshift
• Reduction in positioning time, depending on various machining states, such as roughing
and finishing
Assignable specification of the active exact stop criterion
The active exact stop criterion can be permanently specified for the part program commands
of the first G-group irrespective of the exact stop criterion programmed in the part program.
